In Moscow, President Barack Obama and other world leaders are meeting for the regular Group of 20 conference. But potential military conflict in Syria is hanging over the ostensibly economics-centered meeting.

Obama attends the conference as the U.S. Congress considers his request for authorization of military force in Syria. He'll spend time with nations opposed to military intervention, particularly China and Russia.

At the meeting, the deputy finance minister in China, Zhu Guangyao, expressed concerns that an attack on Syria would cause oil prices to rise.
